SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps anticipate and mitigate potential failures by writing a post-mortem before shipping a project, ensuring that risks are identified and addressed early.

Core Features & Use Cases

  • Risk Identification: Write a post-mortem in past tense to reveal potential failure modes.
  • Mitigation Planning: Hardened top risks through redesign, gating, or acceptance.
  • Use Case: Before launching a new feature, run a premortem to anticipate and prepare for potential issues.

Quick Start

Run the premortem skill with the command: /premortem the new onboarding flow

Frequently Asked Questions about premortem

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is a premortem in project management and how does it prevent project failure?▼

To run a premortem, write a hypothetical post-mortem in past tense as if your project has already failed. Identify specific failure modes, then categorize risks based on likelihood and impact to prioritize mitigation efforts during project planning.

Can I use a premortem for risk assessment on small feature launches?▼

Yes, a premortem is designed for project planning and risk management at any scale. Running a premortem before launching a new feature helps anticipate potential issues and prepare mitigation strategies early in the development cycle.

What is the difference between a premortem and a standard post-mortem?▼

A standard post-mortem analyzes failures after they occur, while a premortem assesses risks before shipping by writing that same analysis in advance. This shifts risk identification earlier, allowing you to mitigate issues during project planning.

How are identified risks handled after a premortem analysis?▼

After a premortem identifies failure modes and categorizes them by likelihood and impact, top risks are hardened through redesign, gating, or acceptance. This ensures high-priority risks are actively mitigated before the project ships.
